IPC: F01N3/28
Filed: 1986-05-21
Abstract: PURPOSE:To obtain a carrier prevented from the clogging of cells and improving the flow of exhaust gas, by a method wherein a carrier comprising a flat plate and a corrugated iron sheet is divided into a plurality of sections and the wavelength and wave height of the downstream side corrugated iron sheet are set to 1/n those of the upstream side corrugated iron sheet and the wave forms of the corrugated iron sheets are abutted at adjacent surfaces to integrally constitute said sheets. CONSTITUTION:A metal carrier is divided into a plurality of sections A, B from the inflow part of exhaust gas toward the outflow part thereof. When the wave height of an upstream side corrugated iron sheet 32 is set to (h) and the wavelength thereof to (l), the wave height of a downstream side corrugated iron sheet 42 is set to h/2 (n is an integer of 2 or more) and the wavelength thereof to l/n and both sheets are laminated so that the wave forms of them are shifted by a half wavelength. Therefore, the upstream side carrier and the downstream side carrier can be integrally constituted in such a state that the wave forms thereof are superposed at the end surfaces of said carriers and pressure loss at adjacent surfaces can be prevented. By this method, a carrier wherein each cell opening is made large in an exhaust gas inflow side to delay the clogging of the cell opening due to the adhesion of lead concentrated to the inflow side to a large extent and synthetic properties are also excellent is obtained.

Title: Power conversion device and phase-locked control method therefor
Inventor: SAKURAI YOSHIMI
IPC: G01R29/18
Filed: 1997-05-07
Abstract: PROBLEM TO BE SOLVED: To swiftly synchronize a power conversion device after restoration of a commercial alternating-current power supply. SOLUTION: A phase-locked control circuit 10 exercises control and performs arithmetic operation in order to match the operating frequency of current commands of a power conversion device (converter) 3 which the frequency of an alternating-current power supply. In this phase-locked control circuit 10, the proportional and integral (PI) control operation system of a frequency control circuit 14 is changed by means of a switching signal from a circuit 13 which detects failure and restoration of the alternating-current power supply 1. When an anomaly of the power supply such as instantaneous power failure or power failure occurs, integrating operation is stopped. When the power supply is restored, the integrating operation is restarted.  Since the operating frequency does not largely deviate during the period of an anomaly, the synchronization of the power conversion device with the commercial alternating-current power supply is realized in a short time after the power supply is restored. If the power conversion device 3 is a converter, as shown in the figure, operation with the power factor 1 of input current is swiftly achieved. If the power conversion device is an inverter, stable power is immediately supplied to a load.

Filed: 1990-05-07
Abstract: PURPOSE:To enhance a light shielding rate and to reduce a film thickness by adopting the constitution contg. two colors of pigments having complementary color relations with each other to form the light shielding film. CONSTITUTION:The light shielding film is constituted by incorporating two kinds of the pigments having the complementary color relations with each other. While many of the combinations of two colors of the pigments having the complementary color relations with each other exist and are not particularly limited, pigment-contg. resist agents are commercially marketed for three primary colors; red (R), green (G) and blue (B) and are easily available; therefore, the combination of R and B is more preferable. Others include the combination of yellow (Y) and violet (V), etc. The light shielding film has the high light shielding rate in this way and, therefore, the film thickness is reduced.

Title: Control device for plastic sheet extruder
Inventor: KIMURA HIDEKI
IPC: B29C48/92
Filed: 1979-09-14
Abstract: PURPOSE:To reduce an unevenness in the thickness of a sheet, by a method wherein an extruding amout is estimated by measuring a resin pressure in an extruder, and a sheeting speed is regulated. CONSTITUTION:A relation of Q=kP exists between an extruding quantity Q and a resin pressure P presuming that a proportional constant is k, and an equation of Q=WtV is held, where W is a sheeting width, t is a thickness, and V is a sheeting speed. This is formulated into a formula of t=(k/W)(P/V). The sheeting width W is considered to be almost constant, and thereby V may be controlled according to P so as to keep P/V constant. In a sheet extruder 1, a sheet is rolled out through a flat die 4 by means of a cooling roll 5 to form a sheeting 7. Accordingly, the unevenness in the thickness of the sheet can be reduced by adjusting a winding speed of the cooling roll 5 and the like according to the detected pressure after a resin pressure of the extruder 1 is detected 11.

Title: Exhaust emission control device for lean-burn internal combustion engine
Inventor: TOSHIOKA TOSHISUKE
IPC: F02D41/34
Filed: 1999-04-23
Abstract: PROBLEM TO BE SOLVED: To possibly reduce as much as possible the number of SOx poisoning reactivation control. SOLUTION: A first occulsion and reduction NOx catalyst 8a is arranged on an exhaust passage of an internal combustion engine, which can perform lean burning for low temperature/low load operation. A second occulsion and reduction NOx catalyst 8b is arranged on the downstream side of the first occulsion and reduction NOx catalyst, for high temperature/high load operation. In a device having such a setup, a bypass passage 6b to the second occulsion and reduction catalyst 8b is arranged, while bypassing the first occulsion and reduction NOx catalyst. A changeover valve 25 is arranged for switching exhaust passages to the bypass passage and to the first occulsion and reduction NOx catalyst. Even when the second occulsion and reduction NOx catalyst is exposed to SOx in low-load operation, therefore, SOx poisoning reactivation treatment is not performed.  Only when the second occulsion and reduction NOx catalyst is exposed to SOx in high-load operation, is the SOx poisoning reactivation treatment performed. The number of reactivation control is thus reduced.

Title: Pattern recognition system
Inventor: SATO KOICHI
IPC: G06K9/62
Filed: 1996-05-13
Abstract: PROBLEM TO BE SOLVED: To recognize characters with high efficiency and at low cost by canceling partly or totally a handwrite information recognition routine against the written special characters and the writing way of a person who inputted the characters. SOLUTION: The characters inputted via a handwritten character input means 11 are expanded into various information including the vector, the writing order, the number of strokes, the character shapes, etc., by an input switching means 12. Based on these information, a handwritten character recognition means 13 recognizes characters via a recognition dictionary 15. A right-handed person writes the characters from the left to the right but a left-handed person is liable to write the characters from the right to the left. When a recognition means 18 inputs and designates the left-hander information, the vector information on the dictionary 15 is masked by a dictionary mask designation means 19, i.e., deleted out of the dictionary 15. Then the means 13 refers to the dictionary 15 and recognizes the handwritten characters.  Under such conditions, no dictionary exists for the vector information and the recognition rate is improved even for the characters which are written by the left-handed person.
